Synthesis of core-shell magnetic molecular imprinted polymer by the surface RAFT polymerization for the fast and selective removal of endocrine disrupting chemicals from aqueous solutions

In this study, we present a general protocol for the making of surface-imprinted core-shell magnetic beads via reversible addition-fragmentation chain transfer (RAFT) polymerization using RAFT agent functionalized iron oxide nanoparticles as the chain transfer agent. The resulting composites were characterized by X-ray diffraction (XRD) and Fourier transform infrared (FT-IR) analysis, thermogravimetric analysis (TGA), vibrating sample magnetometer (VSM), and scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The surface-imprinted magnetic beads were demonstrated with a homogeneous polymer films (thickness of about 22 nm), spherical shape, and exhibited magnetic property (Ms = 0.41 mA m² g⁻¹) and thermal stability. Rebinding experiments were carried out to determine the specific binding capacity and selective recognition. The as-synthesized surface-imprinted core-shell magnetic beads showed outstanding affinity and selectivity towards bisphenol A over structurally related compounds, and easily reach the magnetic separation under an external magnetic field. In addition, the resulting composites reusability without obviously deterioration in performance was demonstrated at least five repeated cycles.     

甲基红在壳聚糖上吸附富集的研究

研究了pH、初始浓度、时间及温度对甲基红在壳聚糖上吸附富集的影响。结果表明，pH是影响甲基红吸附富集的重要因素，最佳pH3．4。其动力学行为更好地符合Lagergren准二级反应动力学模型，随着温度增加，平衡吸附量减少。吸附过程的表观活化能（Ea）为7．518kJ／mol。壳聚糖对甲基红的吸附过程较好地符合Freundlich吸附等温方程。计算得到吸附过程的热力学参数△G0、△H0。和△S0分别为-24．88kJ／mol（303K）、-22．15kJ／mol和8．783J／（mol·K），表明壳聚糖对甲基红的吸附是一个自发的放热过程。红外光谱分析得到，壳聚糖吸附甲基红的过程中，壳聚糖分子中存在的大量羟基和氨基发挥了主要作用。     

Empirical Research on Factors Influencing Level of Environmental Protection Information Disclosure in Annual Reports by Listed Companies

Taking 248 A-share manufacturing listed companies in 2006 Shanghai Stock Exchange as example, using ＂index method＂ to measure level of environmental protection information disclosure, this paper examines the factors influencing level of environmental protection information disclosure. The findings show that the disclosure level has improved, but the overall level is still low and unable to satisfy information users; there is positive correlation between corporate size, industry type, accounting firm＇s type and corporate environmental disclosure index. The companies of large scale and heavy pollution and those audited by international ＂Big 4＂ and domestic ＂Big 10＂ accounting firms have a high level of environmental disclosure, while the profitability and financial leverage has no impact on the disclosure level. Finally some suggestions are put forward to establish environmental information disclosure system in China.     

远离H1N1，我们能做到……

甲型H1N1流感病毒：猪流感是由猪流感病毒引起的一种急性呼吸道传染病，这种病在猪中经常发生，但很少导致猪的死亡。通常情况下，人类很少感染猪流感病毒。     

坚持安全发展 推进综合监管——访国家安监总局副局长梁嘉琨

近年来，我国各级安全生产监管部门全面落实科学发展观，坚持安全发展的理念，认真履行安全生产综合监管职能，积极探索开展综合监管工作的措施、途径和手段，逐步构筑了“分类指导、职责明晰、条块结合、运行有序、机制完善”的安全生产综合监管机制和总体格局，全国安全生产综合监管建设取得了长足的进步。但是，在综合监管工作实践中，很多地区也都遇到并提出了同样的问题：《安全生产法》等法律法规中并没有对综合监管的内容作出明确的规定。     

Dynamic Evaluation on Regional Tourism Competitiveness： Urban Agglomeration of Shandong Peninsula, Eastern China

The article establishes the appraisal index system for entire urban agglomeration and its interior cities individually, concretely including five aspects： driving forces for tourism development, the level of tourism development, tourism impacts, tourism economic connection and tourism contributions of different cities to the whole urban agglomeration. As tourism competitiveness has the characteristics of comprehensiveness, systematicness and dynamicness, the article attempts to apply the structural prediction means of system dynamics to evaluating tourism competitiveness, aiming to provide some research methods and analysis ideas for tourism competitiveness measurement and trends analysis in urban agglomeration. Taking Shandong Peninsula urban agglomeration as the study area, the article simulates and analyzes the tourism competitiveness trend of the whole region and its interior cities from 2005 to 2020, and the result reflects that integrated development and regional combination of tourism are important means to upgrade tourism competitiveness in this region.     

金华生态建筑的设计

金华生态建筑是自身良性循环的绿色建筑物，有3个特点，即屋顶覆土种植或养殖或设太阳能装置，地下设有以净化生活污水为主要目的沼气净化池，墙体垂直绿化，这三者缺不一可，但可单项利用，它有节土，节水，节能和经济，环境，社会产益协调统一这两大优点。     

生态规划实效性评价指标体系研究——以《太仓生态市建设规划》实效性评价为例

首先提出了生态城市规划实效性的内涵,包含规划目标实现程度、规划效益、公众主观感受和规划实施过程合理性等4个方面。在此基础上建立包括规划编制过程、规划实施过程和规划实施结果3个阶段,涵盖政府、企业和公众等不同主体行为和利益特征的从过程到结果,具有复合价值观的规划实效性评价指标体系。通过太仓生态市建设规划实效性评价案例研究做了进一步论证:①生态城市规划主管部门是规划实效评价的主要推动者;②从过程到结果的评价思路和评价指标具有可操作性和灵活性;③规划过程评价方法的不成熟使其受到的关注有所降低。最后提出了若干规划编制和管理建议,以促进生态规划长效管理机制的形成。
